scoring guide

GMAT ORIGINAL PRACTICE — LEARNING GUIDE Award one learning point for a fully correct question. A grouped response is correct only when every required group has exactly its keyed selection and no extra selections. This all-or-nothing learning rule is editorial; no official partial-credit policy is asserted. Record separate counts out of 21 Quantitative, 23 Verbal, and 20 Data Insights, plus a whole-form count out of 64. Do not convert these counts to the official 205–805 scale or use them as a pass/percentile prediction. Official scoring depends on question characteristics and other adaptive conditions unavailable here. No official pretest count or secure pilot positions were identified; all64 questions are original learning items.
